Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to an AOI inspection device that is easy to maintain. Background Technology

[0002] AOI (Automated Optical Inspection) equipment is an automatic inspection device based on optical principles. It is mainly used in the electronics manufacturing industry to ensure product quality. It automatically scans products with a high-definition camera, collects images, and compares them with qualified parameters in a database to detect defects in the products.

[0003] However, when AOI inspection devices produce unclear images, it's impossible to accurately determine if the problem stems from a damaged light source. Furthermore, existing light sources often have high intensity, posing a significant health hazard to manual observation while the light is on. Therefore, we propose an AOI inspection device that is easier to maintain to address these technical problems. Utility Model Content

[0004] In view of this, the main purpose of this utility model is to provide an AOI inspection device that is easy to maintain, and its function is to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a main body of equipment, on which an electric guide rail is fixedly mounted; a double-channel slide block is fixedly mounted on the electric guide rail; a linear motor is mounted on the double-channel slide block; a slide rail is also mounted on the double-channel slide block; the linear motor is connected to the slide rail; a fixed seat is fixedly mounted on the slide rail; a loading frame is fixedly mounted on the fixed seat; a connecting seat is fixedly mounted on the inner side of the loading frame; an adjusting seat is fixedly mounted on the bottom of the connecting seat; a supplementary light is fixedly mounted on the adjusting seat; a connecting plate is mounted on the inner side of the connecting seat; a camera mechanism is mounted on the connecting plate; a lifting mechanism is mounted on the main body of equipment; a lifting seat is mounted on the lifting mechanism; a plug-in plate is fixedly mounted on the bottom of the lifting seat; and a reflector is plugged into the inner side of the plug-in plate.

[0006] As a preferred embodiment, a testing platform is snapped onto the top of the lifting seat, and the testing platform corresponds to the supplementary light.

[0007] As a preferred embodiment, the camera mechanism includes a mounting bracket fixedly disposed on the inner side of a connecting plate, and a lens mount is fixedly disposed on the mounting bracket.

[0008] As a preferred embodiment, a lens is fixedly mounted on the lens mount, and the lens corresponds to the fill light.

[0009] As a preferred embodiment, a reserved slot is provided on the main body of the device and below the supplementary light.

[0010] As a preferred embodiment, the lifting mechanism includes a cylinder fixedly installed inside a pre-reserved slot, and a connecting frame is fixedly provided on the top of the cylinder, the connecting frame being engaged with the lifting seat.

[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0012] This device uses a lifting mechanism on its main body to raise and lower the lifting platform. The adjustable platform allows for adjustment of the distance between the object and the lens, resulting in a clearer image. A connector plate fixed to the bottom of the platform is used to mount the reflector. The reflector, inserted into the inner side of the connector plate, is used to check for damage to the LEDs inside the supplementary light. By removing the inspection platform, the reflector is directly exposed to the supplementary light. Turning on the supplementary light allows the lens to capture an image of the reflector, enabling convenient self-checking of the supplementary light. This helps users quickly and accurately determine if the problem lies with the LEDs inside the supplementary light when image quality issues arise, facilitating timely troubleshooting of unclear images and avoiding health hazards associated with direct observation by maintenance personnel.

[0021] Please see Figures 1 to 4 This utility model provides an AOI inspection device that is easy to maintain, including a main body 1, an electric guide rail 2 fixedly mounted on the main body 1, a double-channel slide block 3 fixedly mounted on the electric guide rail 2, a linear motor mounted on the double-channel slide block 3, a slide rail 4 mounted on the double-channel slide block 3, the linear motor connected to the slide rail 4, a fixed seat 5 fixedly mounted on the slide rail 4, a loading frame 6 fixedly mounted on the fixed seat 5, a connecting seat 7 fixedly mounted on the inner side of the loading frame 6, an adjusting seat 8 fixedly mounted on the bottom of the connecting seat 7, a supplementary light 9 fixedly mounted on the adjusting seat 8, a connecting plate 10 fixedly mounted on the inner side of the connecting seat 7, a camera mechanism mounted on the connecting plate 10, a lifting mechanism mounted on the main body 1, a lifting seat 17 mounted on the lifting mechanism, a plug-in plate 19 fixedly mounted on the bottom of the lifting seat 17, and a reflector 20 plugged into the inner side of the plug-in plate 19;

[0022] In use, the electric guide rail 2 fixedly mounted on the main body 1 controls the reciprocating linear displacement of the dual-channel slide block 3. The dual-channel slide block 3, fixedly mounted on the electric guide rail 2, connects to and slides on the electric guide rail 2. The dual-channel slide block 3 has two sets of connection ports, which are slidably connected to the electric guide rail 2 and the slide rail 4 respectively. A linear motor mounted on the dual-channel slide block 3 drives the slide rail 4 to reciprocate linearly. The slide rail 4, also mounted on the dual-channel slide block 3, is used to mount the fixed base 5. The linear motor moves together with the fixed base 5. The linear motor is connected to the slide rail 4. The connection between the linear motor and the double-channel slide 3 is mainly achieved by mounting the mover onto the double-channel slide 3. For a flat linear motor, when the linear motor is powered on, the mover generates a thrust on the double-channel slide 3, thereby causing the slide rail 4 to move linearly. The linear motor can effectively transmit the thrust to the slide rail 4 to achieve precise linear motion. The connection components between the mover and the linear motor, the double-channel slide 3 and the slide rail 4 are existing mature technologies and will not be described in detail in this article.

[0023] The fixed seat 5, which is fixedly installed on the slide rail 4, is used to load the loading frame 6. When the slide rail 4 moves linearly, the slide rail 4 drives the fixed seat 5 to move together, and the fixed seat 5 drives the loading frame 6 to move together. The loading frame 6, which is fixedly installed on the fixed seat 5, is used to load the connecting seat 7. The downward extension length of the connecting seat 7 can be adjusted on the loading frame 6 to adapt to the camera of the lens 13. The connecting seat 7, which is fixedly installed on the inner side of the loading frame 6, is used to load the adjusting seat 8. The adjusting seat 8 and the connecting seat 7 are fixedly connected by a screw plug. When the supplementary light 9 is damaged... When needed, the adjustment base 8 and the connecting base 7 can be disassembled. The adjustment base 8, which is fixedly installed at the bottom of the connecting base 7, is used to support the fill light 9. The fill light 9, which is fixedly installed on the adjustment base 8, is used to provide supplementary lighting during the shooting process of the lens 13. In night or low-light environments, the fill light 9 can provide the necessary illumination to ensure that the lens 13 can capture clear and realistic images. Furthermore, the fill light 9 of this device has an umbrella-shaped structure, and the LEDs inside the fill light 9 are distributed in a multi-level ring on the inner side of the fill light 9, thereby achieving a reasonable light ratio and lighting arrangement. The fill light 9 can... To highlight the subject and make the image clearer, the LEDs are a mature existing mechanism and will not be elaborated further in this article. The camera mechanism located inside the connecting plate 10 is used to photograph the object being inspected for subsequent AOI inspection. A lifting mechanism on the main body 1 drives the lifting seat 17 to rise and fall. The adjustable lifting seat 17 allows for adjustment of the distance between the object and the lens 13, resulting in a clearer image. A connector plate 19 fixed to the bottom of the lifting seat 17 is used to mount the reflector 20. The reflector 20 inserted inside the fill light 9 is used to check whether the LEDs inside the fill light 9 are damaged. After the test platform 18 is removed, the reflector 20 is directly exposed to the fill light 9. By turning on the fill light 9, the lens 13 takes a picture of the reflector 20, which enables a convenient self-test of the fill light 9. This helps users to determine in a timely and accurate manner whether the LEDs inside the fill light 9 are damaged when there is a problem with the image. This facilitates timely repair of whether the unclear image is due to a problem with the light source, and avoids the health hazards caused by direct observation by maintenance personnel.

[0024] Please see Figure 3 The top of the lifting seat 17 is fitted with a detection table 18, which corresponds to the supplementary light 9;

[0025] When this device is in use, the detection platform 18, which is snapped onto the top of the lifting seat 17, is used to support the item to be tested. The detection platform 18 and the lifting seat 17 can be easily disassembled. After the detection platform 18 is removed, the device can easily perform self-testing on the supplementary light 9. The lifting seat 17 and the reflector 20 are interconnected. After the detection platform 18 is removed, the reflector 20 is directly exposed to the supplementary light 9.

[0026] Please see Figure 3 The camera mechanism includes a mounting bracket 11 fixedly disposed inside the connecting plate 10, and a lens mount 12 fixedly disposed on the mounting bracket 11;

[0027] When this device is in use, the mounting bracket 11 fixedly installed on the inner side of the connecting plate 10 is used to load the lens mount 12. After loading, the lens mount 12 and the lifting seat 17 are in a vertical position. The lens mount 12 fixedly installed on the mounting bracket 11 is used to fix the lens and ensure that it remains stable during shooting.

[0028] Please see Figure 3 A lens 13 is fixedly mounted on the lens mount 12, and the lens 13 corresponds to the fill light 9;

[0029] When this device is in use, the lens 13 fixedly mounted on the lens mount 12 is responsible for capturing and focusing light to form an image. The lens 13 corresponds to the fill light 9, and the fill light 9 covers the outside of the lens 13, with the internal LED beads distributed in a ring around the lens 13 to provide it with a light source.

[0030] Please see Figure 1 A reserved slot 14 is provided on the main body of the equipment 1 and below the supplementary light 9;

[0031] When this device is in use, the reserved slot 14 on the main body 1 and below the supplementary light 9 is used to store the lifting seat 17, and the height of the lifting seat 17 can be adjusted according to the height of the item to be detected, so as to facilitate AOI detection of the item.

[0032] Please see Figure 1 The lifting mechanism includes a cylinder 15 fixedly installed inside the reserved slot 14, and a connecting frame 16 fixedly installed on the top of the cylinder 15. The connecting frame 16 is engaged with the lifting seat 17.

[0033] When this device is in use, the cylinder 15 fixedly installed inside the reserved slot 14 is used to control the lifting of the connecting frame 16. The connecting frame 16 fixedly installed on the top of the cylinder 15 is used to load the lifting seat 17 and drive the lifting seat 17 to move linearly together.
